AIRQN FOB, FIBER-TREATING MACHINES.

To all whom "it may concern Be it known that I, Gnome J. Tonmncng a citizen of the United States, and a resident of Harrison, county of Hudson, and? have invented certain new and useful Improvements in Aprons for Fiber-Treating Machines, of which the following is a specification. This invention relates to a device which= is attached to fiber treating machines and is adapted to convey the fiber and waste from the main cylinder of a card and to return The invention relates more particularly to a device of this kind which consists of a conveyer which is built up of a series of strips or slats arranged side by side, the slats being shaped at their edges so that the two edges of adjacent slats will form a pocket for dirt, these pockets being emptied when the slats are passed over the roller or pulley at the point where the fiber is taken from the conveyer to be returned to the card.

Another feature of the invention is the arrangement at intervals of a felted or fibrous strip to catch the waste and fiber from the main cylinder of the card and hold it until it is picked up by the fibrousseizing device which returns the fiber to the card. The separation of the abrasive or tlufi'y fibrous strips on the conveyer provides smooth spaces between them over which the fiber easily passes, and the fiber also passes over the pockets previously described because it is light and it passes along the belt on which it is held by one of the fluffy or felted strips, but the dirt settles in the pockets, and in this way the belt, or con veyer acts to separate the fiber and the dirt to a great extent, and the fiber that is delivered back to the card from the belt is not mixed with dirt, the dirt being in the pockets where it is not picked up by the fiber-returning device.

The invention is illustrated in the accompanying drawing, in which- Figure l is a diagrammatic view showing a small portion of a card as commonly used, showing the general relation of the parts to the conveyer, the conveyer being illustrated as underneath the main card broken away at its right hand end. Fig. 2 is an Specification of Letters Patent. Application filed April 11, 1814.

enlarged side view of the conveyor, one of the strips being shown in elevation to illustrate the means of attaching it :to the belt or hand, and Fig. 3 is a broken view illustrating the belt shown in Fig. 2 in plan.

It will be understood that in the drawing the machine, part of which not shown, is not the only form of machine in which the invention is used, but is merely shown to clearly describe the invention and as an instance of itsnse. Enough of the machine, however, is shown to enable any one skilled in the art to apply the device, theillustration showing a main cylinder 11 and a tumbler 12 with a bur-cyliiuler 1.3. Adjacent to the tumbler is a pick-up device or brush 14: which is adapted to take fiber from the belt or apron to be hereinafter described and which comprises my invention.

The apron or belt passes over suitable rollers or pulleys 15, one of which is shown in Fig. 1 and Fig. 2, the other end of the belt, which is not shown, passing over any similar rotative element to make the passage of the belt easy. These rollers are operated in any suitable way from a source of power, the belt being disposed underneath the main cylinder 11 so that it catches the fiber that falls from the main cylinder, along with the dirt and the extraneous material. The belt is usually made up by providing several bands 16, these bands being of leather or any other suitable material that is provided for the purpose, this acting to secure the traction over the pulleys 15, and also acting to support the strips or slats 17. The strips or slats are arranged side by side and they abut on the belt when the belt is flat, and they are provided at their side edges with cut-away portions that form pockets between the strips. The usual way of doing this is to chamfer the side edges of the strips as at 18, the strips coming together at the bottom, as at 19, so that a series of pockets 20 are formed. The smooth beveled side edges are preferred because they form smooth surfaces over which the dirt and grit are dropped, when the pockets are in position to be emptied, by reason of the natural movement of travel of the belt.

These pockets act as receptacles or depressions into which the dirt that passes from the card with the fiber settles. As the mawithout departing from the scope of the invention.

Having thus described my invention, I claim 1. A conveyer for fiber treating machines comprising an apron having its outer face 5 provided with pockets and gathering strips at separated points on the apron so that several pockets are between adjoining strips, said strips being constructed to retain loose, fiufi'y fiber, the face of the apron being 6 smooth to permit the easy passage of said fiber over the pockets.

2. A conveyer for fiber treating machines comprising an apron having its outer face provided with transverse pockets, and strips at separated points between said pockets so that several pockets are between adjoining strips, said strips being of a material to re g tain'loose, fluffy fiber passing along the face of the apron. I

A conveyer for fiber treating machines comprising an apron, said apron having parallel strips arranged side by side, the abutting faces of thestrips being cut-away to form pockets between the strips, and top layers or strips of material to retain loose, fluffy fiber arranged on separated apron strips in order to present several pockets between adjoining strips.

a. A conveyer for fiber treating machines comprising a belt having on its outer face a series of slats arranged side by side, the slats having their adjacent edges beveled, the slats being arranged with their bottom edges in contact, whereby the beveled edges form pockets, strips of material on separated slats, said strips being constructed to retain light, fiufi y fiber passing over the belt, the slats etween the covered slats be ing smooth to ermit the easy passage over said slats of said loose fiber.

In testimony that I claim the foregoing,

I have hereto set my hand, this 10th day of April, 1914:.

terial from the card settles on the belt it passes over the smooth top of the strips, and the dirt being heavier, falls into the pockets 20. but the fiber slips along the top surface of the belt.

In order to gather the fiber so as to convey it up to the picking-01f device 14, I provide separated strips with a covering on the top of felt or other fibrous material that has a slightly uneven surface that will hold the light, fiufiy fiber that descends on the apron. The slats that are provided with this catching or gatherin strip are separated so that there is a chance for the dirt to separate from the fiber before the fiber is engaged by a strip. I have found that a good way to do this is to equip every other slat or strip with a strip of fibrous material 21, whereby every alternate strip is left plain and smooth. In this way there are two pockets arranged between each felted strip and the next felted strip so that the dirt settles in the pockets 20, and the amount of dirt that is caught with the fiber on the felted strips is very small. The fiber is picked up by the device 14 and started on its return to the main card, the material in the pockets not being engaged by the picking-up device or brush it and is therefore held in the pockets until .it is emptied by the slats being carried over the roller 15 and the pockets being opened to permit the dropping out of dirt, which is clearly shown at 22 in Fig. 1.

I prefer to fasten the strips 17 to the bands 16 by means of rivets 28 which pass through the transverse center of the strips so that the beveled side edges of the strips are free to adjust themselves to the movements of the belt. The under side of the rivets are countersunk as at 24 and headed, the countersunk heads 24. thus providing a smooth under surface for the bands 16 so that the engagement or fitting over the pul leys or belts 15 is good.

It will be understood that the particular description of the manner of fastening the Witnesses: strips to the bands and other minor details M. A. JorINsoN, are not essential, and may be altered slightly H. TRAUTVETTER.
